Cov khoom siv hlau siv dav siv hauv kev tsim kho, kev tsim khoom, thiab lwm yam xws li H-shaped steel, lub kaum sab xis steel, thiab U-channel steel

H BEAM: Ib qho I-puab steel nrog sib npaug sab hauv thiab sab nrauv flange. H-shaped steel yog categorized rau dav-flange H-shaped steel (HW), nruab nrab-flange H-shaped steel (HM), nqaim-flange H-shaped steel (HN), nyias-walled H-shaped steel (HT), thiab H-puab pawg (HU). Nws muaj kev khoov siab thiab compressive zog thiab yog hom hlau siv dav tshaj plaws hauv cov qauv hlau niaj hnub.

Lub kaum sab xis steel, tseem hu ua lub kaum sab xis hlau, yog cov khoom siv hlau nrog ob sab ntawm lub kaum sab xis. Nws yog categorized li qhov sib npaug-ceg kaum steel los yog tsis sib npaug-ceg kaum steel. Cov lus qhia tshwj xeeb yog qhia los ntawm sab ntev thiab tuab, thiab tus qauv naj npawb yog nyob ntawm qhov ntev hauv centimeters. Lub kaum sab xis steel sib npaug ntawm qhov loj 2 txog 20, thaum lub kaum sab xis tsis sib npaug ntawm qhov loj ntawm 3.2/2 mus rau qhov loj 20/12.5. Lub kaum sab xis steel muaj cov qauv yooj yim thiab yooj yim rau nruab, ua rau nws siv dav hauv cov qauv hlau, cov khoom txhawb nqa, thiab lwm yam kev siv.

U-channel hlauyog U-shaped steel bar. Nws specifications qhia nyob rau hauv millimeters li haunch qhov siab (h) × ceg dav (b) × haunch thickness (d). Piv txwv li, 120 × 53 × 5 qhia tau hais tias ib txoj kab uas muaj qhov siab ntawm 120 hli, ib ceg dav ntawm 53 hli, thiab lub taub hau tuab ntawm 5 hli, los yog 12 # channel steel. Channel steel muaj zoo dabtsi yog khoov tsis kam thiab feem ntau yog siv los txhawb cov qauv thiab nyob rau hauv cov cheeb tsam uas muaj peev xwm load-bearing.
